Abstract
589,934. Two-part couplings. SOUTH WALES SWITCHGEAR, Ltd., and FARRER, S. April 3, 1945, No. 8190. [Class 38 (i)] [Also in Group XXXVII] A socket contact member comprises a number of contact fingers 4, held disposed about the axis of the socket by flexible members 3, which permit the fingers to move bodily towards or away from the axis of the socket, resilient means, such as helically wound strips 7 of phosphor bronze, restraining bodily movement away from the axis. The strips 3, each of which may comprise a closed loop of tinned copper foil, support the fingers from the block 1. When a plug 6 is inserted, the fingers 4 may move parallel or obliquely to the axis of the socket to provide alignment with the plug. Movement of the individual fingers towards the axis is limited by a projection 8 from the block 1, as shown in Fig. 1 or by a washer gripped between,the fingers 4 and loosely held to the block 1 by a bolt, Fig. 4 (not shown). In a further modification, Fig. 5 (not shown), movement of the fingers is restricted by an annular co-axial projection of the block 1 carrying pins which engage slots in the fingers 4. In all forms the fingers are sufliciently concave to ensure line contact with the plug.
